Things to check before you call for service:
- Check to see if your thermostat is set correctly.
- Replace thermostat batteries. (only if batteries are required)
- Check the air filter.
- Check to see if the furnace cabinet doors are secured. (loose cabinet doors can disengage the door switch)
- Make sure all air vents are open and air is blowing. (If little or no air is blowing then turn the thermostat off and call for service immediately)
- Check to see if the main AC breaker is in the on position. ( Try reseting the breaker by turning the breaker all the way off and then back on)
- Make sure the furnace power switch is in the on position. (It looks like a light switch that is connected to the furnace)
If all checks are completed and it’s still not working then turn the system to the off position at the thermostat and call for service immediately. Never try a diy heating and air repair beyond this point unless you are a licensed HVAC contractor.
Things home owners can do that will improve system performance:
- Change the filter regularly
- Open all air vents
- Wash outdoor coil with water hose. (acid cleaning will still need to be performed periodically but washing with water may prolong the need to have this done)
- Have a licensed company perform regular maintenance. (Once a year for the heating and air conditioning)
- Have a programmable thermostat installed if you don’t already have one. (saves hundreds of dollars a year)
- Remove limbs, bushes, shrubs, debri or grass that may be choking the outdoor portion of your air conditioner.
- Clean air ducts every 10 years. Back To Home Page
